摘　　要：目的使用不同参数的图片刺激志愿者以使其产生视觉诱发电位(visual evoked potential,VEP),通过分析其VEP的特征参数来探究3D图片的不同参数对人体的影响,以期解决3D电视引发的人体生理不适问题。方法以Neuroscan脑电仪为核心设备构建了实验测试系统,选取10名健康男学生,在接受图片刺激出现自身感觉不适时做出按键反馈。通过对整个实验过程中采集的脑电信号叠加平均的方法提取VEP,并用统计学方法分析不同参数图片与VEP之间的关系。结果所有图片均能刺激产生相似的实验波形和典型成分,但在不同亮度下P2成分的幅值出现明显差异,而在不同类型之间其潜伏期又有所不同。结论 P2成分可作为检测不同3D影像的特征参数。Objective In order to solve the discomfort problem in human body evoked by 3D-TV, we explore the effect of different parameters of pictures on human body by using pictures with different parameters to stimulate volunteers to produce visual evoked potential （VEP） and through the analysis of characteristic parameters of VEP. Methods A VEP test system was set up centered on Neuroscan electroencephalograph. Ten healthy male students were requested to accept picture-stimulation of different parameters. When the volunteers felt discomfort,a feedback button would be pressed. VEP was extracted through averaging EEG signals and a statistic analysis was made to find the relevance of the pictures with different parameters and VEP. Results All images could induce similar experimental waveforms and typical ingredients,yet images generated by different parameters induced latencies and amplitudes different. Conclusions P2 can be used as a characteristic parameter to detect different components of a 3D image.
